KlNG-BOLT FOR VEHICLES.

ESPECIFICATION forming part of Letters Patent No. 376.618, dated January17, 1888. Application filed December 17, 1886. Serial No. 321.813. (Nomodel.)

- T0 aZZ whom i may concern:

Be it known that I, DANIEL D. WHITNEY, a

-citizen of the United States, residing at Cornwall, in the county ofOrange and State of New York, have in vented certain new and usefulImprovements inKing-Bolts and Means for Lubricating the Same, of whichthe following is such a full, clear, and exact description as willenable any one skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, forming partof this specification.

The object of my invention is to secure a king-bolt that is easy tomanufacture, can be adjusted in position readily, is durable, and givesa great bearing-srirface. My invention has also for its Object toprovide mcaas and devices whereby the king-bolt can be expeditiously andeffectively lubricated. I accomplish these objects by means of thedevices hereinafter to be described, the novel features of which will bepointed out in the claims.

I will proceed now to give a detailed description of the devicesillustrated in the accompanying'drawings, forming part of thisspecification, in which- Figure 1 represents a side elevation of devices embodying the invehtion; Fg. 2, a sectional elevation through thecenter and at right angles to the plane of Fig. 1; Fig. 3, a. detailview showing the sleeve surrounding the kingbolt, which sleeve sustainsthe weight of the vehicle and has grooves or recesses for the receptionof a solid lubricant; and Fig. 4,- a sectional view of a modificationcorresponding to Fig. 2.

In thedrawings, D represents the kingbolt, which has a clip portion, B,adapting it to be fastened over the wooden part of the axle A, which isprovided at its lower part with an iron piece, F, upon the outer ends ofwhich latter are formed the journals upon which the wheels of thevehicle are borne. The clip may be fastened to the members A and Fin anysuitable manner-such, for instance, as a crossbar and two nuts, as shownin the drawings. I do not wish to confine my invention to a clipking-bolt, as it may be applied to any king-bolt. Upon the conicalportion of the 50 king-bolt D bears a sleeve, a, which has reis the sameas before.

ccsses in it for the reception of a solid lubricant. This sleeve c hasresting upon it a plate, I), a portion of the sleeve projecting up intothe plate b, so as to afford a longer bearing for the sleeve upon theconical.portion of the king-bolt. Fig. 3 shows the shape of this sleeve,which is secured to the head-block C by serews which pass through theholes shown in this figure, and also through the holes in plate b, whichcan be fastened to the head block by means of serews ofits own. I haveshown the plate b as secured in place also by a clip, E, which embracesthe springs G of the vehicle and passos down through ears ff of thisplate and is firmly held in place by means of nuts. This clip is notindispensable, and I represent it only to show the mechanism complete.Through these springs passos the kingbolt upward through the clip E, andhas a nut,

e, upon its upper end, which holds the parts together.

The clip E is of course serviceable when the Springs G are used, as itserves to hold these springs to the head-block. l Vhen the springs aredispensed with, the clip E can be dis- 7 carded.

In Fig. 4 is shown the preferred form of my invention, in which thesleeve a is modified and made not to project so far below the plate b asiu the previous instance, thus making a more finished and clegantappearance than the arrangement represented before, while at the sametime the efficiency and durability of the apparatus are in nowayinterfered with and the bearing of the sleeve a upon the king-bolt 85 The head block and plate b are a tritle cut away and the sleeve a madeto project farther upinto the head-block.

In the device shown in this figure, also, I interpose a metal washer, d,having perforations 0 "therein, into which is paeked a solid lubricantbetween the nut e and its bearing. This decreases the frietion and wearwhich naturally would take place between the nut and the bearing or clipE, upon which it would otherwise rest. By this means the resistance tothe movement of the axle and swiveling motion of the kingbolt isgreatlylessened. This is a feature of my invention.

So far as I am aware I am the first to apply a solid lubrieant to akingbolt substantially f the construction described, and, also, I belleve myself to be the first to provide a king holt which has a coniealbearing of the charactor set forth, one in which the bearing is not upona shonlder, both of which featuresl claim to be highly advantageous, theformer by reason of the fact that lubrication is more read ily andeflectively accomplishcd by the means I have shown, and, seeondly,because it is more convcnient, doing away with oils, which drip and runover the vehicle, so that where one attempts to wash or sponge off thesame the spongc becomes covered with grease, which is then carried toother parts of the vehicle by the cleaner. This same obj ection isnoticeable in fifthwheels. In auotherpending application, No. 218,171,filed November G, 1886, I h ave provided means to overcome thisobject1onable feature in the lattcr class of devices. It will also beobserved that I secure a larger bearing-snrfaee by means of the coniealarrangement described than can be attained by direct abutment of thebearing-surfaces iu a king-bolt. Tosetasidealldoubtsas to whether therewould bc any wedging action between the king-bolt and the sleeve a, sothat they would not rotate upon each other, but would, when greatpressure was thrown upon them, be locked together, I experimented uponthe same by serewing the nut c down as tightlyas possible; but evenunder these eircumstances the sleeve a and kingbolt could be rotatedwith facility, thus setting aside all doubts as to the operativeness ofthe means described.

I do not wish to confine myself to the exact means described, as thesame may be varied w1thout departing from my invention, and I reservethe right to make all changes within the scope of what I desire to claimand secure by Letters Patent, which is 1. A conieal king-boltforvehicles and a conical sleeve or other means co-operating therew1th,within which the king-bolt rotates, fastened to the head-block, forsustaining the weight ofa vehicle by the conieal portion alone.

2. The combination of a conieal-clip kingbolt, as B D, a head-block, asC, within which the king-bolt rotates, and a sleeve, as a, con- 5oforming to said king-bolt and fast to said head-block, operatingessential] y as set forth, supporting the weight of a vehicle by theconieal portion alone.

3. The combination of a conieal-clip kingbolt, as B D, a headblock, asC, a plate, as b,

fast thereto, and a sleeve, as a, within which the king-bolt rotates,upon which the latter rests, secured to the same and to the head-block,all operating essentially as set forth, sustaining the weight by theconieal portions alone.

4. The combination of a conicalclip kingbolt, as B D, a headblock, as C,a plate, as b, fast thereto, having cars, asff, and a clip, as E, forholding the same in place through the instrnmentality of said cars, anda sleeve, as a, within which the king-bolt rotates, upon which thelatter rests secured to the same and to the head-block, sustainiu g theweight by the conieal portions alone.

5. The combination of a conieal clip kingbolt, as B D, a head-block, asC, aplate, as l), fast thereto, having cars, asff, and a clip, as E, forholding the same in place through the instrumentality of said cars, asleeve, as. a, within which the king-bolt rotates,upon which the latterrests secured to the same and to the head-block, and a washer, as d,having recesses carrying a solid lubricant interposed between the nut cand its bearing, sustainiug the weight by the conieal portions alone.

6. The combination, in a kingbolt having a conieal portin, as D, i'orsustaining the pressure, of a sleeve, as a, within which the kingboltrotates, eonforming thereto and cooperating thcrewith, having grooves orchannels, as c, filled with a graphite composition for the purposespecified, and means for securiug said sleeve to the head-block in anysuitable mauner and the king-bolt to the axlc.

7. The combination, in a king-bolt having a conieal portion, as D, forsustaining the press ure, of a sleeve, as a, within which the kingboltrotates, conforming thereto and co-operating therewith, having groovcsor channels, as c, filled with a graphite composition for the purposespecified, a washcr, as d, having a graphite composition packed iurecesscs therein interposed between the nut c and its bearing, and meansfor securing said slceve to the head-block in any suitable manncr andthe kiug-bolt to the axle.

In testimony where0f I have hercunto set my hand and scal, this 16th dayof December, 188G, in the presence of the two subscribing witnesses.
